Patent EP-0109402-B1 (EP)
Title: Solutions catalytiques permettant d'activer des substrats non conducteurs et procede de placage sans passage de courant electrique
IPC: C23C18/28
Filed: 1983-03-02
Granted: 1988-06-01
Abstract: Composition d'activation améliorée permettant de préparer des substrats pour effectuer une métallisation dans un bain de placage sans passage de courant électrique. Un procédé amélioré est également décrit pour activer des substrats avant d'effectuer la métallisation, ainsi qu'un procédé amélioré de métallisation utilisant le procédé d'activation amélioré. Le dépôt sans passage de courant électrique qui consiste à réduire chimiquement les ions du métal à plaquer à partir du bain de placage et sur une surface activée d'un substrat, est amélioré en utilisant un acide organique dans le bain d'activation qui active la surface du substrat. Des bains d'activation préférés contiennent des ions halogénure de palladium pour former une surface catalytique sur le substrat, des ions halogénure stanneux pour former un sol protecteur, une source d'ions d'un halogénure supplémentaire, et un acide organique tel que des acides citriques ou tartariques. La composition et le procédé permettent l'élimination d'une étape d'accélération conventionnellement requise, tout en donnant des résultats d'une qualité sensiblement supérieure spécialement avec des substrats ayant des trous traversants nécessitant un revêtement, tels que des plaques à circuits imprimés sur lesquelles doit être effectué un placage de cuivre.

Abstract: For digital signal processing with a transversal filter having a (N-1) stage delay chain which is fed at its input with the digital signal to be processed and is provided with taps, subsum signals are stored which correspond to the N/w consecutive groups of, in each case Aw possible combinations of, in each case, w consecutive, A-value tapped signal elements, where the subsum signals are formed from tapped signal elements which are each assigned to a group and are evaluated in accordance with the relevant filter setting. During each delay stage, in accordance with the relevant N/w actual combinations tapped elements, the associated subsum signals are successively read from a memory and added to one another to form an output signal element. The subsum signals can be iteratively formed in that each of the successively-read subsum signals, combined with a correction value, forms a corrected subsum signal which is stored in place of the read subsum signal as a new subsum signal.

Abstract: The invention provides a method of preparing a detector which is sensitive to ionising radiation or atomic emissions. The method includes the steps of forming at least two discrete conductive regions (10, 12) on a counting diamond (14) by ion implantation, at a temperature below 500 DEG C. Subsequently, contacts (16, 18) are applied to the conductive regions to allow charged carriers liberated by the radiation to be detected by an electronic circuit. The invention extends to a detector prepared according to the method. An example of a detector according to the invention comprised a synthetic diamond having a paramagnetic nitrogen impurity concentration of less than 150 parts per million. Two conductive regions were formed on the diamond by bombardment with carbon ions, and contacts were formed on the conductive regions by the applications of silver-loaded epoxy paint.
